Remote sensing information extraction of the Laizhou Bay environment pollution
莱州湾环境污染遥感信息提取试验

Information was extracted from remote sensing images over a period of 40 years for environmental pollution about seven sewage outlets into the Laizhou Bay. The results were in agreement with multiple previous survey results. Increase of water pollution of the Laizhou Bay by discharge was revealed by the color changes and pixel analysis of outfall since the 1990s, confirming that the ecological environment of the Laizhou Bay was worsening. Sea surface temperatures, chlorophyll concentration distributions, and oil spill of sea surface of the Laizhou Bay in the 2011 were retrieved from MODIS and ENVISAT-ASAR data. The sea surface temperature and chlorophyll concentrations of the Laizhou Bay near shore were on the high side and the danger of marine oil spill was expanding. This study shows that Remote Sensing technology is a good method to extract information of environment pollution in the sea area and can be used as effective means of water pollution control.
